2 shot after a man fires into large crowd gathered to watch a street race in Southwest Philadelphia, police say

PHILADELPHIA (WPVI) -- Police said a woman and a man were injured when a gunman opened fire on a large crowd in Southwest Philadelphia early Sunday morning.

Police said hundreds of people were gathered outside the BP Gas Station on the 6500 block of Essington Avenue, a popular spot for street racing.

According to investigators, an argument broke out between two groups of people around 2:30 a.m.

Police said a man driving a three-wheeled Polaris Slingshot pulled out a gun and fired at least 16 shots into the crowd, with one of those bullets hitting a 31-year-old woman and another striking a 48-year-old man .

The woman was taken by police to Penn Presbyterian Hospital where she is in stable condition with a gunshot wound to her thigh.

Police said the man was shot once in the abdomen. He was taken to Delaware County Memorial Hospital in critical condition.

Investigators said everyone left the scene following the shooting, but detectives are hoping surveillance cameras from the gas station and a nearby car dealership will help them with the case.
